Re: show that f(x) has a removable discontinuity...

I have the function f(x) equal to 3/x+(-2x + 6)/[x(x-2)] when x different to 0, and 2,

and f(x) equals 9 when x = 0

I have to show that f(x) has a removable discontinuity at x=0

I'm stucked with the transformation of these fractions and it leads me nowhere, can you show me please the first few steps?

I also tried to put it in LaTeX but I got something wrong, (see below)

If the limit from the left of zero is equal to the limit from the right of zero AND that limit is a finite number then the function will have a removeable discontinuity. Calculate the 1 sided limits as x--> 0
